This power bank suits travellers and heavy phone users who want several phone charges, fast top-ups, and enough output for a phone, earbuds, and a tablet together on trips and long days.

33W maximum output over USB-C charges phones and tablets quickly with PD and QC 3.0 support (use a cable rated for 33W or above for the best speed). The USB-C port also recharges the power bank itself at up to 30W input. Two USB-A ports add more outputs, and you can charge three devices together. The 20000mAh (74Wh) capacity gives several full phone charges. 12-layer safety protection and input overvoltage protection guard your devices, and a low-power mode handles small devices like earbuds and smartwatches. The durable PC+ABS body suits daily carry.
